Falling/ Rising Film Evaporator

A Falling/Rising film evaporator is an industrial equipment to concentrate solutions, especially with heat sensitive components. The evaporator is special type of heat exchanger. The Evaporation takes place inside the vertical tubes.

In case of Falling film Evaporator the process fluid to be evaporated flows downwards by gravity as a continous film. The fluid will create a film along the tube walls, progressing downwards. The vapors are collected into vapor separator and flows into Condenser.

In case of Rising film Evaporator the process fluid to be evaporated flows upwards by means of vacuum as a continous film. The fluid will create a film along the tube walls, progressing upwards. The vapors are collected into vapor separator and flows into Condenser.
